NIAGARA FALLS -- A Wheatfield man was allegedly assaulted and several people were robbed by three men, at least one of whom had a gun, inside a Welch Avenue home early this morning.

The 18-year-old man told police he called another man over to the home, between 24th and 25th streets, to sell him a quarter-pound of marijuana, according to a city police report.

The man arrived with two other men just before 1 a.m. The victim was struck in the face with a gun, then knocked out after he was struck in the back of the head. The other people in the house were ordered to get down on the floor.

The robbers then took several purses, which contained cash and cell phones, as well as the marijuana, according to the report.
